Can anyone throw some light on why I cannot get 'pyinstaller' to execute successfully?

The installation of pyinstaller seemed to be successful but every time I run it on the simplest of scripts, it fails on message:

IOError: [Errno 2] No such file or directory: '/usr/local/lib/python2.7/dist-packages/PyInstaller/bootloader/Linux-32bit-arm/run'

I think you need to build the bootloader for Raspbian: Building the Bootloader

The instructions for Debian/Ubuntu should work on Raspbian, too, but do not add the repository as stated, just install the packages.


Full Tutorial

After many hours of searching, I got this working. The answer is straightforward, but it is spread across multiple StackExchange answers and GitHub Issues. I put it all together in this tutorial, so I save some hours for the next poor soul.

Key Takeaways

  • pip ships PyInstaller with the incorrect architectures. You need to build it yourself for ARM (Raspberry Pi).

Step by Step

1. Build the bootloader

git clone https://github.com/pyinstaller/pyinstaller 
# Alternatively download the zip from https://github.com/pyinstaller/pyinstaller/releases
cd pyinstaller/bootloader
python ./waf distclean all # or python3
cd ../PyInstaller/bootloader/

Here you should see Linux-32bit-arm and inside of it run and run_d

2. Check the bootloader

file Linux-32bit-arm/run

run: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=a01c65d74d7d8b483800154dcdd4a5d2aad95d5b, stripped

If you see the above, you are good so far. However, if you see something like ELF 32-bit LSB executable, Intel 80386, that is wrong.

3. Copy the bootloader

If you installed PyInstaller with pip inside a venv, then do this

# Replace ${CLONED_PYINSTALLER_PATH} with the path where you git cloned above
# Replace ${PATH_TO_YOUR_PROJECT} with the path to your project (where you have the venv)

cp -r ${CLONED_PYINSTALLER_PATH}/PyInstaller/bootloader/Linux-32bit-arm ${PATH_TO_YOUR_PROJECT}/venv/lib/python3.5/site-packages/PyInstaller/bootloader/

If you installed with apt-get, then do this

# !!! Replace python3.5 with your version
cp -r ${CLONED_PYINSTALLER_PATH}/PyInstaller/bootloader/Linux-32bit-arm /usr/local/lib/python3.5/dist-packages/PyInstaller/bootloader



SystemError: objcopy Failure: objcopy: Unable to recognise the format of the input file `$FILE`


`file dist/$FILE`

If it does not say ELF 32-bit LSB executable, ARM [...], but instead says Intel or x86, the PyInstaller tries to use the incorrect bootloader. If you executed all steps above, try renaming the Linux-32bit-arm to just Linux-32bit. That seems to have worked for this user


gcc not found


sudo apt-get install build-essential

Adding on to the point made by S.Spieker in his answer... I suspect that the path for the compilation of the bootloader is wrong for your platform.

Rename the directory, as mentioned in the forum, Pyinstaller missing Linux-32bit-arm/run:

cd /usr/local/lib/python2.7/dist-packages/PyInstaller/bootloader
sudo mv Linux-32bit Linux-32bit-arm
